ANTI-FRICTION BEARING.

' SPECIFICATION forming part of Letters Patent No. 444,224, dated January 6, 1891. Application filed August 18, lilQO- Slerial No. 362,381.(No model.)

city and in the county of San Francisco, and

State of California, have invented certain new and useful Improvementsin Anti-Eric tional Bearings; and I do hereby declare the following tobe a full, clear, and exact descrip tion of said invention, such as willenable others skilled in the art to which it most nearly apperlains tomake, use, and practice the same.

My invention has relation to certain new and useful improvements inanti-frictional bearings, which consists of the details of constructionand arrangement of parts, as will be hereinafter more fully shown in thedrawings described, and pointed outin the specifition.

The object of my invention consists in providing for the verticalarrangement of the bearing-rollers above the axial line of the rotatingshaft, so that only the periphery of the lower one shall contacttherewith, andat the same time located relatively to one another in lineof greatest pressure and friction, thereby relieving the shaft of unduefriction.

My invention further consists in providing a self-lubricating hearingwhich shall be simpler of construction, less expensive, and moreefieotive in its operation than any device of a similar natureheretofore known to me.

Referring to the drawings forming a part of this application, in whichsimilar letters of reference are used to denote corresponding partsthroughout the entire specification and several views of the drawings,Figure 1 is a vertical sectional view in side elevation, and Fig. 2 afront view in elevation, partly broken away.

The letter A is used to indicate the outer casing, within which theanti-frictional rollers are movably secured. The inner faces of thelower end of said casing are somewhat enlarged or cut away, as shown atb so as to receive the journal-box B. The outer faces of saidjournal-box are channeled, so as to form guides which embrace thewallsaof the casing, thus providing against the displacement thereof.The journal-box has a limited vertical movement within the cut-awayportion of the casing, for the purpose hereinafends of axles e e.

ter set forth. The shaft C passes through the journal-box opening 0,formed centrally in box B, and inasmuch as the sameis of less diameterin the center thereof, as shown at o, is securely held in its adjustedposition by means of the inner downwardly-projecting walls I) of thejournal-box B, as shown in Fig. 1. Said journal-box projects intochamber A, within which the waste is held, and the same has the openingformed in its bottom, so as to allow of the waste contacting with theshaft 0.

The inner faces of the outer-casing walls a have the channels at formedtherein, within which the small journal-boxes-cl d fit. W'ithin thesesliding journal-boxes I secure the The axle e is provided with thebearing-roller E, which works within' the opening 6 formed in the top ofthe journal-box B, as clearly shown in Fig. 1, and contacts with shaft0, secured within said journal-box. The axle c has secured thereon theguide-rollers E E, the peripheries of which bear against axle e on eachside of roller E. Above said guide-rollers I locate the roller E, whichworks between the guide-rollers and upon the axle e and obtainsitsmotion therefrom. The axle e projecting from said roller, may work injournal-boxes similar to However, if so desired, these boxes may bedispensed with and the ends of said axles move within the verticalgrooves or channels cl, or they may be otherwise secured and guided. Thebearing-roller E is secured directly above roller E, the object being tobring the same in line with the greatest pressure.

to theguide-rollers E, the peripheries of which bear against the axle ofbearing E, and these in turn transmit their motion to bearing E f,permit the 1:1assage of oil therethrough,

which contacts with the axle thereof. Owing Y to the varying size of thewheels, the motion imparted to hearing E is considerably slower thanthat of bearing E, which contacts directly with the journal-shaft. Anynumber of bearings may be secured within the casj ing, each so arrangedas to receive motion from the other and to be in line of pressure.However, if so desired, bearing E may be dispensed with withoutmaterially affecting the operation of my invention.

While the bearings herein shown and described appear from practicalexperiments sufiicient to carry out my invention, still, however, amultiple of bearings may in many cases considerably lessen friction.Consequently I do not wish to be understood as confining myself to thenumber herein shown.

I am also aware that the location of the bearings may be varied. V

In order to properly lubricate the several 1 bearings, I provide at. theupper end or top of the casing the oil-receptacles F F, which have the(lischargeorificc thereof so located as to fall in line with the guidesformed in the walls of the outer casing. Thus the oil first lubricatingthe upper hearings will pass on to the upper journal-boxes, which, beingsupplied with openings f, allow of a free passage thercthrough into thelower boxes, which, being also provided with oil-openings from whence itfalls into receptacle or chamber A, which thoroughly saturates the wastecontained therein, and inasmuch as the same contacts with shaft 0 tendsto maintain the same continually supplied with oil, hence preventing hotboxes.

\VhileI have shown my invention employed in connection with arailway-ear axle, it is obvious that the same may be applied to allclasses of machinery wherein it is desirous that the friction thereof bereduced.

I am aware that minor changes may be made in the arrangement of partsand details of construction herein shown and described withoutnecessitating or creating a departure from the nature and scope of myinvention.

llaving thus described my invention, what I claim as new, and desire tosecure protection in by Letters Patent of the United States, is

1. In an anti-frictional bearing, the combil nation, with the casingthereof, of the movable shaft journal-box located in the lower portionthereof, shaft secured within said journal, guidechanncls formed withinthe casingwalls, and the successive bearings secured within the casingand adapted to move within the side channels, substantially as set forthand described.

In an anti-frictional bearing, the eombination, with the outer casingthereof, of movable shaft-journal located within the lower portion,guide-channels formed in the inner face i of the casing-walls,journal-boxes working within the channels, bearing-rollers workingwithin said boxes, and the guide for maintaining the bearing-rollers inrelative position, substantially as set forth and described.

3. In an anti-frictional bearing, the combination, with the casingthereof, of bearingrollers secured therein, oil-reservoir located insaid casing, said reservoir communicating so as to lubricate thebearing-rollers automatically, and the movable shaft journal-box,substantially as set forth and described.

4-. In an anti-frictional bearing, the combination, with the casingthereof, of the movable shaft journal-box secured within the lowerportion of the casing, upper and lower openings formed in said ,journalbox, and the multiple bearings working within the casing, as set forthand described.

5. In an anti-frictional bearing,thc combination, with the casingthereof, of lOVl'Gx chamher or compartment for reception of waste,movable shaft journal-box secured within the casing, said box havingopenings in its top and bottom, bearing-rollers working within thecasing, and suitable bcaringroller guides for maintaining the hearingsin positiou,suhstantially as set forth and described.

6. In an anti-frictional bearing, the combination, with the slidingjournal-box, of frame or casing within which said box is movable in thedirection of greatest pressure, bearingwheel contacting with thejournal-shaft and having its shaft ends journaled so as to move inguides or channels formed within the easing, and a second wheel orwheels bearing upon the axle of the first wheel and having its shaft inlike manner journalcd in movable boxes in the line of pressure,substantially as set forth and described.

7. In an anti-frictional bearing, the combination, with the shaftjournal-box movably secured within the casing and extending into thelower chamber thereof, said box adapted to move in line of greatestpressure, of bearing-roller located above the shaft ournal-box andadapted to contact with journal-shaft working therein, said bearingbeing movably secured within the casing in the line of press- 11 re,guide-rollers located above the bearingrollers and contacting with theaxle thereof, said guide moving in line of greatest pressure, movableupper bearing-roller contacting with the axle of the guide-rollers andmoving in correspol'iding direction therewith, and the lubricating-oilreservoir located in the upper portion of the casing and provided withdischarge-orifice, substantially as set forth and described.
